Installing a self-signed certificate

You can install a self-signed SSL certificate on your hosting.com account for testing and development purposes. To do this, you create a private key and digitally sign your own SSL certificate in cPanel.
ImportantUsers receive warning messages in their browser when they try to access a web site secured by a self-signed certificate. This is because a trusted Certificate Authority has not signed the certificate. cPanel SSL certificates are readily available for cPanel accounts and are a trusted Certificate Authority in most browsers. For more information about cPanel SSL certificates, please see Securing a cPanel-enabled account with a cPanel SSL certificate.
To create and install a self-signed SSL certificate, follow these steps:
  1. Log in to cPanel.
    📘 Note If you do not know how to log in to your cPanel account, please see this article.
  2. On the Tools page, in the Security section, click SSL/TLS:
  3. Under Private Keys (KEY), click Generate, view, upload, or delete your private keys. The Private Keys page appears.
  4. Under Generate a New Private Key, confirm that the Key Type is set to RSA, 2,048-bit.
  5. In the Description text box, type a descriptive name for the key, such as Self-signed cert key.
  6. Click Generate. cPanel generates and displays the private key.
  7. Click Return to SSL/TLS.
  8. On the SSL/TLS page, under Certificates (CRT), click Generate, view, upload, or delete SSL certificates. The Certificates page appears.
  9. Under Generate a New Certificate, in the Key list box, select the description for the private key you generated in step 6.
  10. In the Domains text box, type the domain that you want to secure with the self-signed certificate, such as test.example.com.
  11. Complete the remaining fields for the certificate.
    🚧 Important Make sure you use the correct two-letter country code (for example, US or FR). For a complete list of these codes, please visit http://www.iso.org/iso/country_codes/iso_3166_code_lists/country_names_and_code_elements.htm .
  12. Click Generate. cPanel generates and displays the self-signed certificate.
  13. Click Return to SSL/TLS.
  14. From the SSL/TLS page, under Install and Manage SSL for your site (HTTPS), click Manage SSL sites. The Manage SSL Hosts page appears.
  15. Under Install an SSL Website, click Browse Certificates, select the certificate you generated in step 12, and then click Use Certificate. cPanel fills in the Certificate (CRT) and Private Key (KEY) fields automatically.
    📘 Note Because this is a self-signed certificate, the Certificate Authority Bundle (CABUNDLE) field remains blank.
  16. In the Domain list box, select the domain you want to secure with the certificate.
  17. Click Install Certificate. cPanel installs the certificate on the server and enables SSL. When the process is complete, you receive an SSL Host Successfully Installed message.
  18. Click OK. You can now securely access the specified domain by using the https:// prefix in a web browser, but you will receive a warning message about the self-signed certificate.
